ELECTRIC STOP-MOTION FOR WARPlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 443,674, dated December 30, 1890.

Application filed January 11, 1890. Serial No. 336,654- (No model.)

To all whom, it may concern.-

Be it known that I, PHILIPP GOLDSCHMIDT, ofPaterson, in the county of Passaic and State of New Jersey, have invented a certain new and useful Improvement in Electric Stop-Motions for lVarping-Machines, of which the following is a specification.

My improvement relates to stop-motions employed in machines for warping, and is particularly adapted to machines for the warping of silk.

I will describe my improvement in detail,

and then point out the novel features in claims.

' In the accompanying drawings, Figure 1 is a side elevation of a portion of a warpingmachine and a stop-motion embodying my improvement. Fig. 2 is a plan or top view of thesame. Fig. 3 is a view on an enlarged scale of a portion of the stop-motion, the said view being partly in section. Fig. 4. is a detail partly in section and partly broken away and looking in the direction of the arrow, Fig.3.

Similar letters of reference designate corresponding parts in all the figures.

In carrying out my improvement I take threads from-a creel, and after passing them through a reed deliver them onto a drum. After leaving the drum they pass to a spool. In passing over the drum they cause the rotation of the latter by friction. The drum drives indicator mechanism by which the number of yards of thread passing to the spool is measured. In conjunction with the indicator mechanism I employ a stop-motion, which.stop-motion is operated, when a sufficient number of yards has been passed to the spool, to stop the machine. I further cause the operation of the same stop-motion electrically to cause the stopping of the machine upon the breaking of a thread-passing from the creel.

I will first describe the passage of the thread to and over the drum and the operation of the indicator mechanism.

Threads A are delivered from a creel A. (Shown as in the main of ordinary construction.) Spools w are arranged upon spindles w. The threads pass upwardly and over a rod 10 near the upper end of the creel. After leaving the rod w they pass through a reed w and from thence separately through fallerwires w. The faller-wires w are shown as pivoted near their lower ends upon a metallic bar 10 secured upon but insulated from the creel. They are provided with curls or eyes 20, through which the threads extend. Beyond the curls or eyes to they have straight portions 10 The threads in passing through the curls or eyes to operate to maintain the faller-wires in an elevated position. Should one of the threads break, the taller-wire through which it passes will fall and contact with a metallic contact-piece w, extending widthwise of the creel and mounted upon but insulated from arms w, extending from the creel. \Vhen the faller-wire falls, it operates as a circuit-closer to close an electric circuit and cause the operation of a stop-motion to stop the machine in a manner to bepresently described. The thread after leaving the fallcr-wire passes over glass rods a. Alternate threads pass over and under said rods, so as to cross each other in a well-known manner. From the rods a the threads pass beneath a rod a, and from thence onto and over the drum B. The drum B is journaled, as at a in brackets B, extending upwardly from the frame B of the machine. The threads in their passage overt-he drum impart rotary motion to the latter by friction. Upon the shaft of the drum is mounted a worm I), which worm meshes with a worm-wheel I), mounted on a vertically-extending shaft 12 journaled in the frame B and also in a bracket B extending upwardly from said frame. The upper end portion of the shaft b carries a worm b which worm meshes with a worm-wheel I), mounted upon a shaft Z), journaled in the bracket B G designates an indicator-dial. This dial is scored upon its face and near its periphery to indicate the number of yards of thread which it is desired to wind upon a spool. This dial is loosely mounted on the shaft 17".

C designates a hand-whecl, which handwheel is provided with a hub c, secured on the dial 0. The handwheel and hub also loosely surround the shaft b Although I have stated that the dial, hand-wheel, and hub loosely surround said shaft, I wish it to be understood that'they are held in frictional contact with said shaft, so that when the shaft. rotates they will rotate with it.

Assuming that it is desired to place three hundred and sixty yards upon the spool, the wheel C is operated by hand, and the indicator-dial is thereby rotated from Zero progressively toward the number 360 and until said number is opposite a given point. .In this instance such point is a toe (Z on a lever (1, which lever is fulcrnmed upon a bracket (1 extending upwardly fromthe bracket B The toe d occupies a position vertically and directly over the dial. At the zero-point on the dialis a notch d. The dial having been set as described and the machine put in operation, the dial rotates toward thezero-point, and when it reaches the zero-point the toe (Z willdrop into the notch d, which will'resn'lt in operating a stop inotion for the machine, to be presently described. I

The driving mechanism between the drum B andth'e indicator-dial is so timed that the l rotation of the drumwill deliver only the de- 'fsiji cdnumberof yards ot' warp onto the spool that is provided for in the adjustment of the designates -a main driving-shaft jouriia'led in; suitable bearings upon the main frame. "This shaft derives motion from a fast 'pulley g on the main shaft. Said main shaft is also provided witha loose pulley g- I have shown 'a stop-motion for stopping the iiiachine when the proper quantity of warp has been received upon the spool. iVhen the toe d uponthe lever (1' drops into the notch at the zero-point on the dial G,-a rod H, suspended from a horizontally-extending rod H, connected with the lever (2, also falls, such fall being occasioned bygravity. The rod H slides vertically in suitable bearings in an upright-I and is provided with ahorizontally-extending tooth or projection 1'. (Shown more clearly in Fig. 4.) provided with two transversely-extending apertures i i Referring more particularly to Figs. 3 and 4, J designates a rod adapted to move to and fro through the aperture i in the upright 1. Longitudinal movement is imparted to the rod J from an eccentric J on the shaft G by means of an eccentric-rod J one end of which connects with one arm of a bell-crank lever J the other arm of which has connected to it the rod J. The bell-crank lever J is fulcriuned upon the frame 13. The other end ofthe rod J is connected by means of a crosshead or yoke J to a rod .1, which rod is adapted to be moved to and fro through the opening in the upright I and also through a suitable opening in abraclcetj", extending upwardly from the frame 13*. The cross-head o -yoke J hasa loose connection with the 'rodJ, so that it may under certain circum- The upright I is rod and is interposed between the crosshead or yoke J 4 and a collar upon the rod J. The resistance of this spring is such that when the passage of the rod J 5 is unobstructed through the aperture '5 in the upright I the cross-head or yoke J will cause longitudinal movement of the rod J \Vhen the 'rod II posite the aperture 1 and thus prevent longitudinal movement of the rod J tinned reciprocation of the rod Jis, however, permitted, owing to the spring J..

Pivoted upon the rodJ is a lever J which lever has a loose connect-ion near its lower end (as shown being held between pins) with the cross-head or yoke J hen the rods J J 5 are reciprocating in unison, ans lever moves with the rods; but-when the movement of the rod J 5 has been stoppedthe lever J? is its fulcrum. It then operates to raise a trip jection Z u pona1ever L. The lever L is fulcrumed near the base of the frame B? and has connected to it one end of a belt-shifterrod L3, which belt-shifter rod carries at itsother end a belt-shifter L by which the belt may be shifted from the fastto the loose pulley, or vice versa.

In the operation just described the belt is shifted to the loose pulley, and the machine is therefore instantly stopped. The movement of the lever in one direction or in the direc; tion to stop the machine is facilitatedby a spring L connected thereto and to the frame B The machine is again started, of course, by rotating the dial O sufiieiently to raise the toe at out ofthe notch 61 and again operating the lever L to engage it with the trip I). 1

Secured to the lower end of the rod H, but insulated therefrom, is an armature P. This armature is adapted to be attracted by an electro-magnet P. One pole of thelnagnet is in circuit with a battery F. From the other pole a wire a extends to the metallic crossbar 10 upon which the fallr-wires 10 are pivoted. A wire it extends from the metallic cross-bar 10 to the other pole of the battery P lVhen a thread breaks and the tallerwire drops upon the metallic cross-bar 10 circuit will be closed on the electro-magnetP' and the armature P will be attracted. This will cause a sidewise swinging movement of the rod II, which will cause said rod to extend across the opening 2' in the upright I", thus closing said opening and preventing longitudinalmovement of the rod J ,.whereupon a similar action will occur to effect the stoppage of the machine to that previously described. iVhen the faller-wire which closed circuit has been again raised to breakcitcuit, the armature P will swing backwai'dly from the electro-ma'gnet-P, thus again uncovering the opening 1' and admitting of the operation of the machine. I .e

rotate with the dial and are adapted to come in contact with a circuit-closcrO, which may be of any suitable kind, mounted upon the From this circuit-closer a wire 0 extends to the battery, and another wire 0' extends from the circuit-closer to a bell-signal R, of ordinary construction. From the bellsignal R- a wire 0 extends to the other pole of thebattery. \Vhen one of the pinso comes in contact with the circuit-closer O to close circuit, an audible signal will be given, which will indicate the number of yards already passed over the drum. Of course I may use any desired number of the pins 0.

I have not illustrated the spindle mechanism nor the means for operating the same, as the same does not broadly constitute part of my invention, and by their omission I have been enabled to give larger and clearer views. It will be seen that by my improvement I am enabled to employ a single stop-motion controlled both by the rotation of the dial and also by the breaking of a thread from the creel, this stop-motion being operated through the movement of a single rod.

IVhatI claim as my invention, and desire to secure by Letters Patent, is

1. In a warping or similar machine, the combinatiomwith a single stop-motion, of a dial for indicatingthe number of yards of threads being wound, a rod moved in one direction when the dial has rotated to a certain point to cause the operation of the stop-motion, a creel provided with taller-wires through which the threads being wound pass, contact-pieces through which circuit is closed by any of said taller-wires upon the breaking of a thread passing through the same, a battery, an elec' tric circuit, .and an electro-magnet operating when circuit is closed by the falling of a tailorwire to move said rod to operate the said stopmotion, substantially as specified.

2. In a warping-machine, the combination, with a rotary dial provided upon its face with pins or projections and a creel provided with taller-wires through which the threads being wound pass, of circuit-closers upon which circuit may be closed by said pins and fallerwires, a single stop-motion under the control of an electric circuit closed by either the pins on the dial or faller-wires, a battery, an electric circuit, and a signal, substantially as set forth.
